• Transit sailing coverage is about 70~90% of Scientific Cruise.
• Seafloor mapping data during transit need to be reviewed for sharing with international scientific community.
• Scientific Cruise Plan hope to be consulted under scientific party.
• To Encourage data sharing, National Government law must be improved with financial support.
Need a Transit Cruise Design
![Page 26: INVENT17 (Indian Ocean Thermal Vent Mapping ... - GEBCO](https://reader034.fdocuments.us/reader034/viewer/2022042612/62637e59cda1e2698c29cd37/html5/thumbnails/26.jpg)
• RV ISABU can map full ocean depth globally since 2017.
• Transit sailing are very valuable, then must be to organize for future demands.
• To share seafloor mapping data with international scientific group, we will develop official way to submit under Each Country Laws or Funding ORG’s Permission.
